By doing this, the vehicle shiftsdown to the next gear and hasmore power.
D(Drive) can be used when towingatrailer,carryingaheavyload,or driving on steep hills. You mightwant to shift the transmission to alower gear selection if thetransmission shifts too often.
Downshifting the transmission inslippery road conditions could resultin skidding. See“Skidding”underLoss of Control0167.
The vehicle has a shift stabilizationfeature that adjusts the transmissionshifting to the current drivingconditions in order to reduce rapidupshifts and downshifts. This shiftstabilization feature is designed todetermine, before making anupshift, if the engine is able tomaintain vehicle speed by analyzingthings such as vehicle speed,throttle position, and vehicle load.If the shift stabilization featuredetermines that a current vehiclespeed cannot be maintained, thetransmission does not upshift andinstead holds the current gear.
In some cases, this could appear tobe a delayed shift, however thetransmission is operating normally.
The transmission uses adaptiveshift controls. Adaptive shift controlscontinually compare key shiftparameters to pre-programmedideal shifts stored in thetransmission’scomputer.Thetransmission constantly makesadjustments to improve vehicleperformance according to how thevehicle is being used, such as withaheavyloadorwhenthetemperature changes. During thisadaptive shift control process,shifting might feel different as thetransmission determines the bestsettings.
The shift quality of a new vehiclemay not be ideal because theadaptive shift control process maynot have determined the bestsettings for a particular shift orcondition. Shift quality will improvewith continued driving.
When temperatures are very cold,the transmission's gear shiftingcould be delayed, providing more
stable shifts until the engine warmsup. Shifts could be more noticeablewith a cold transmission. Thisdifference in shifting is normal.
M:This position lets drivers selectthe range of gears appropriate forcurrent driving conditions. If thevehicle has this feature, see“RangeSelection Mode”underManualMode0186.
3:This position is also used fornormal driving. It reduces vehiclespeed more than D (Drive) withoutusing the brakes. You might choose3(Third) instead of D(Drive) whendriving on hilly, winding roads; whentowing a trailer, so there is lessshifting between gears; and whengoing down a steep hill. See“RangeSelection Mode”underManualMode0186.
2:This position reduces vehiclespeed even more than 3 (Third)without using the brakes. You canuse 2 (Second) on hills. It can helpcontrol vehicle speed as you godown steep mountain roads, butthen you would also want to use the

If you manually select 2 (Second) inan automatic transmission, thetransmission will start insecond gear. You can use thisfeature for reducing the speed of therear wheels when trying to start thevehicle from a stop on slippery roadsurfaces.

When you shiftto 1 (First) it provides the lowestgear appropriate to current roadspeed and continues to downshiftas the vehicle slows, eventuallydownshifting to 1 (First) gear. Thetransmission can be held in 1 (First)gear using Range Selection Modeor the shift lever. See“RangeSelection Mode”underManualMode0186.
Caution
Spinning the tires or holding the
vehicle in one place on a hill
using only the accelerator pedal
may damage the transmission.
The repair will not be covered by
the vehicle warranty. If you are
stuck, do not spin the tires. When
stopping on a hill, use the brakes
to hold the vehicle in place.

Brakes
Antilock Brake
System (ABS)
This vehicle has an Antilock BrakeSystem (ABS), an advancedelectronic braking system that helpsprevent a braking skid.
When the vehicle begins to driveaway, ABS checks itself.Amomentarymotororclickingnoisemay be heard while this test is goingon, and it may even be noticed thatthe brake pedal moves a little. Thisis normal.
If there is a problem with ABS, thiswarning light stays on. SeeAntilockBrake System (ABS) WarningLight0104.
If driving safely on a wet road and itbecomes necessary to slam on thebrakes and continue braking toavoid a sudden obstacle, acomputer senses the wheels areslowing down. If one of the wheelsis about to stop rolling, the computerwill separately work the brakes ateach wheel.
ABS can change the brake pressureto each wheel, as required, fasterthan any driver could. This can helpyou steer around the obstacle whilebraking hard.
As the brakes are applied, thecomputer keeps receiving updateson wheel speed and controlsbraking pressure accordingly.
Remember: ABS does not changethe time needed to get a foot up tothe brake pedal or always decreasestopping distance. If you get tooclose to the vehicle in front of you,there will not be enough time toapply the brakes if that vehiclesuddenly slows or stops. Alwaysleave enough room up ahead tostop, even with ABS.

system might indicate that an oilchange is not necessary for up to ayear. The engine oil and filter mustbe changed at least once a yearand, at this time, the system mustbe reset. Your dealer has trainedservice people who will perform thiswork and reset the system. It is alsoimportant to check the oil regularlyover the course of an oil draininterval and keep it at the properlevel.
If the system is ever resetaccidentally, the oil must bechanged at 5 000 km (3,000 mi)since the last oil change.Remember to reset the oil lifesystem whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever theengine oil is changed so that thesystem can calculate the nextengine oil change. To reset thesystem:
1. Turn the ignition key to ON/RUN with the engine off.
2. Fully press and release theaccelerator pedal slowly threetimes within five seconds.
3. Turn the key to LOCK/OFF.
If the CHANGE ENGINE OIL SOONmessage comes back on when thevehicle is started, the engine oil lifesystem has not reset. Repeat theprocedure.
Automatic Transmission
Fluid
When to Check and Change
Automatic Transmission Fluid
It is usually not necessary to checkthe transmission fluid level. The onlyreason for fluid loss is atransmission leak or overheatedtransmission. If a small leak issuspected, use the followingprocedures to check the fluid level.However, if there is a large leak, itmay be necessary to have thevehicle towed to a dealer and haveit repaired before driving the vehiclefurther.
Change the fluid and filter at theintervals listed inMaintenanceSchedule0297,andbesuretousethe transmission fluid listed inRecommended Fluids andLubricants0305.
How to Check Automatic
Transmission Fluid
Because this operation can bedifficult, it is recommended to havethis check done at your dealer,which can monitor the transmissiontemperature. The transmission fluidlevel increases with temperature. Toobtain a highly accurate fluid levelcheck, the transmission temperaturemust be measured.
If it is decided to check the fluidlevel, be sure to follow all theinstructions here, or a false readingon the dipstick may occur.

outside temperatures, the fan speedincreases as the clutch more fullyengages, so an increase in fannoise may be heard. This is normaland should not be mistaken as thetransmission slipping or makingextra shifts. It is merely the coolingsystem functioning properly. The fanwill slow down when additionalcooling is not required and theclutch partially disengages.
This fan noise may be heard whenstarting the engine. It will go awayas the fan clutch partiallydisengages.
Power Steering Fluid
The power steering fluid reservoir isin the engine compartment on thedriver side of the vehicle. SeeEngine Compartment Overview0218for reservoir location.
When to Check Power Steering
Fluid
It is not necessary to regularlycheck power steering fluid unlessthere is a leak suspected in thesystem or an unusual noise isheard. A fluid loss in this systemcould indicate a problem. Have thesystem inspected and repaired.
How to Check Power Steering
Fluid
To c h e c k t h e p o w e r s t e e r i n g f l u i d :
1. Turn the key off and let theengine compartmentcool down.
2. Wipe the cap and the top of thereservoir clean.
3. Unscrew the cap and wipe thedipstick with a clean rag.
4. Replace the cap andcompletely tighten it.
5. Remove the cap again andlook at the fluid level on thedipstick.
The level should be at the COLDFILL mark. If necessary, add onlyenough fluid to bring the level up tothe mark.
To p r e v e n t c o n t a m i n a t i o n o f b r a k efluid, never check or fill the powersteering reservoir with the brakemaster cylinder cover off.
What to Use
Caution
Use of the incorrect fluid may
damage the vehicle and the
damages may not be covered by
the vehicle warranty. Always use
the correct fluid listed in
Recommended Fluids and
Lubricants0305.
To d e t e r m i n e w h a t k i n d o f f l u i d t ouse, seeRecommended Fluids andLubricants0305.Alwaysusetheproper fluid. Failure to use theproper fluid can cause leaks anddamage hoses and seals.
